The issue you're concerned about is retaining unknown declarations within style rules, not retaining unknown rules. I think if what you were interested in were supporting unknown properties, it would be useful to have an API like the ones described in: https://bugzilla.mozilla.org/show_bug.cgi?id=188321#c14 https://www.w3.org/Bugs/Public/show_bug.cgi?id=14203 Unknown values of existing properties would be a bit harder. > It would be great if UnknownRule was still available, since it'd allow us I think characterizing this as "still available" is misleading.
